Life is a straight line.
You see straight ahead and you keep going.
The grass is green and the sun is shining,
All the cars around you are driving in their own lanes.

Life is a straight line.
Yet the lines on your palm make curves.
the grass is yellow and there are clouds covering the sun,
the lanes keep curving and your car can't keep up

Life is a straight line.
But you can't even walk in a straight line.
the grass has died and the sun has set,
the left turn you made cost you your soul.

Still, life is a straight line.
why are you trying to change that?
